Media Player Classic - BE Win32/x64

[hubi73]

The change between two video clips is now smoother than in build 3788. But since build 3656 (approximately) MPC-BE crashes more often between two videos in a playlist.

The crashes occur every 10-20 video clips, but that one crashes more often than others (almost every time):

The crash occur at the end of that clip before the next clip is opened.

What quality, what filters when playback ??

[chros]

These commits could not so affect. Maybe issue in MS VS C++ compiler ... i don't know.
Hhmm ... the compiler is the same according to the About window:
MSVC 2017, GCC 7.2.0, 58.17.100 / 56.13.100

Something definitely changed between b3533/b3537.

Show filter list when playback.
I tried out with resetting my settings as well (using internal filters), but here it is with a simple mkv file (Video: H.264/AVC 1280x720 23.976fps, Audio: Dolby AC3 48000Hz 6ch 9216kbps, embedded subrip subtitles):
- Lav splitter source + Lav audio decoder + Lav video decoder
- Audio switcher
- MadVR renderer
- MPC audio renderer

Disable LAV filters/madVR/MPC Audio renderer.

[chros]

Disable LAV filters/madVR/MPC Audio renderer.
I can try out tonight.
But can you compile 3 bulds from 3534, 3535, 3536? So we will know for sure which commit is the problem.
I looked at the comitts and the only change is made in the audio renderer.

[hubi73]

@Aleksoid1978
Quality:
mp4 1080p HFR on HDR off >> CRASH
webM 720p HFR off HDR off >> STABLE after short testing

Filters:
external LAV-Filter v0.72
madvr 0.92.14
OS: Windows 10 1607 x64
CPU: AMD A8-7650K

I will test some other quality settings during the day.

1 - test without madVR.
2 - test without LAV.

I use only internal filters, all perfect.

Thank you to the MPC-BE team for MediaInfo v18.08 support in the lastest nightly build.

[chros]

Disable ... MPC Audio renderer.
Thanks, that was a good idea! That's the issue for whatever reason.
I tested with b3537 and set Directsound audio renderer and it worked! If I set it back to MPC Audio renderer it starts crashing again.


But can you compile 3 bulds from 3534, 3535, 3536? So we will know for sure which commit is the problem.
I looked at the comitts and the only change is made in the audio renderer.
So, actually b3534 (https://github.com/jeeb/mpc-be/commit/9ad4f9ed7c966b58168cdaca69c5a59b2dbf17c0) isn't needed since it's just language update.
But one of these commits has the problem:
- b3535 (https://github.com/jeeb/mpc-be/commit/9fe9934d6504da5935beafe69b2708a250c4230b)
- b3536 (https://github.com/jeeb/mpc-be/commit/92c7d2eb16b70105156a0207c70047f65b48049f)
- b3537 (https://github.com/jeeb/mpc-be/commit/25065433ec750ca9548e12463357980a3b7d1873)

I'd vote for the first big one: b3535

So can you compile 2 builds from b3535 and b3536? Thanks

[hubi73]

I moved from external LAV-Spitter to internal Splitter and now every thing is fine. Thank you.

Thanks, but still not good: no crash but mpc-be auto-starts playback.

[SeeMoreDigital]

Hello all,

I've probably missed an obvious function but I don't seem to be able to find out where I can enable a 'frame number' display option.

Is this possible?

[sneaker_ger]

It would be difficult to implement. In containers like mkv you seek to specific times without knowing the number of frames (variable framerate). To be reliable you'd often need to index the entire file.

[Aleksoid1978]

Thanks, but still not good: no crash but mpc-be auto-starts playback.

What can i say - don't use MPC Audio Renderer. I don't know what's wrong and can't help you, sorry ((

[SeeMoreDigital]

It would be difficult to implement. In containers like mkv you seek to specific times without knowing the number of frames (variable framerate). To be reliable you'd often need to index the entire file.Out of interest... Could such a feature be implemented for 'constant' frame rate encoded sources only?

[chros]

What can i say - don't use MPC Audio Renderer.
:) That's the reason why I use MPC-BE instead of MPC-HC.
I don't know what's wrong and can't help you, sorry ((
I know and I understand that it's really hard to figure it out without having replicating the issue locally.
Although We can do one more thing: you can prepare a debug build and I'll upload the logs somewhere.
Thanks for your understanding :)

[chros]

I tested one thing for the last time both with the 2 test builds you made: mpc-be.exe.20180830, mpc-be.exe.20180912
- Only Wasapi Exclusive mode is affected! If I set it to Wasapi Shared mode then it works as it should.

(Note that other nightly builds are not good in both exclusive nor shared mode.)

[hubi73]

Playing web content is always a security risk. Therefore I was happy to use LAV-Filters, because ffmpeg has a pretty good vulnerability management, at least I think so.
Now I'm using MPC-BE's internal Splitter (MPC MP4/MOV Source or MPC Matroska Source) and I'm not sure if they are also ffmpeg based.
So I would like ask, which base has the internal Splitter, is it ffmpeg or something else?

[Aleksoid1978]

All internal source filters - are self writing.

[hubi73]

That sound good to me and I will trust in your skills and carefulness. I was only afraid they were from outside and somehow out of maintenance.

[Aleksoid1978]

Hy all. Test build with suuport new AV1 codec - https://yadi.sk/d/c3NIPEaBptOtjA

[Grimsdyke]

Dual-audio-out in MPC-BE activated and one output is HDMI (TV) and the other is Analog-7.1 (Receiver).
After driver update BE looses the HDMI device and falls back to default and although the TV is set to default in the OS settings there is NO sound !!! So I always have to renew this setting in BE.
This happens also sometimes when I change the refresh rate of the TV.

Microsoft and/or Intel seem to have fixed this long standing issue now !! Foobar runs now flawlessly too. Hurray.

[Grimsdyke]

Latest 64bit-build xx48 does not start because of missing libwinpthread-1.dll !! Does anybody else have this problem too ??

[Zetti]

I got the same problem.

[Klaus1189]

I got the same problem.

I downloaded r3949 and it starts as always, maybe already fixed.

[Zetti]

Build 3948 have the problem and Build 3949 working fine.

[Klaus1189]

In options -> internal filters -> Audio decoder
E-AC3 must (https://en.wikipedia.org/wiki/Dolby_Digital_Plus) be E-AC-3
see here (https://drive.google.com/file/d/1Mm6t3DEff2qTa5S2vvVNbrREcQ5nN0gD/view?usp=sharing)
I don't find a matching string in translation file :confused:

[v0lt]

@Klaus1189
This line is not intended for translation.

[Klaus1189]

OK. I beg to correct it.

[Klaus1189]

@v0lt
Thank you :)

[Mercury_22]

MPC-BE can't see all the "long" playlist when opening a blu-ray including main movie's correct one

While MPC-HC can see it

Sample https://www.sendspace.com/file/2npu9s

[Klaus1189]

A little cosmetic issue is in Options -> Internal Filters -> Tab Source Filters -> Button MPEG splitter configuration
There you can select TrueHD or AC-3 -> the round boxes are cut off at the bottom, maybe we can enlarge that.

Since my desktop resolution is 3840x2160, I use 200% scaling, I tried another pc with 1080p@100% scaling, there it looks fine to me.

[v0lt]

@Mercury_22
Aleksoid1978 changed something in r3963 about this.

@Klaus1189
I corrected the size of radio buttons in r3966. But I checked only in Windows 7.

[Klaus1189]

Thank you v0lt :)

[steakhutzeee]

Hi, as i can see if i change 'styles' on the fly for subs, this works correctly.

If i tweak the 'predefined style' and then select it so i use it for all the videos, i see that the subs is not loaded correctly, i mean, the tags are ignored, like italic etc.

Why this? can i solve?

Thanks :)

ASIO didn't work anymore.

[ryrynz]

Surely this is last beta, it's almost been a year and only for .1 release, why so adverse to releasing stable? Why not have 1.5.2 beta and release 1.5.1.1 with fixes?

[Aleksoid1978]

The release is scheduled for next month, after the purchase of a new certificate.

Bug related to Save image (with subtitle) function.

When using madvr, and the windows size doesn't fit the video size, there would be two subtitles in the screenshot, one in high quality and correct ratio, and one in low quality and incorrect ratio on top.

(Edit: it seems that when using madvr the subtitle would be included even if I disabled the "include subtitle function)

The screenshot of a sup subtitle:

The look in the player.

in case of ass text subtitle, only the spacing is affected, the words would not be stretched.

[Aleksoid1978]

MadVR include subtitles, player can't handle it. See it's options, i think it have settings for subtitles in screenshot.

[v0lt]

MPC-BE 1.5.2 (build 3973) beta (https://sourceforge.net/projects/mpcbe/files/MPC-BE/Nightly%20Builds%20%28from%20svn%20trunk%29/1.5.2%20%28build%203973%29%20beta/) with a digital signature.

OK, I have found that option in madVR. Thanks.

I have a feature request. I probably should have asked earlier, but it didn't seem too important:

https://i.postimg.cc/G2QMbZLm/2-_Fullscreen-_Auto-_Change.png

The feature I'm referring to is the Audio Delay column in MPC-HC that can be applied to specific display modes (refresh rates).

I have one display that has high input lag at 24p, so I have to apply a 150 ms delay to the audio, but only at 24 Hz. The delay is required at 24 Hz, so the existing audio delay in MPC-BE must be adjusted manually per video rather than per refresh rate.

I don't know how common this issue is with modern displays, but there are others out there with the same issues.

Some players besides MPC-HC provide this type of functionality.

Plex Media Player allows for an audio delay at 24 Hz:

audio_delay.24hz (https://plexapp.zendesk.com/hc/en-us/articles/207338798-Advanced-Configuration)

Kodi also allows for an audio delay at any refresh rate:

<refresh>
<min>23</min>
<max>24</max>
<delay>125</delay>
</refresh> (https://kodi.wiki/view/Advancedsettings.xml)

There are some posts out there referencing this issue:

24p and audio sync issues (https://forum.kodi.tv/showthread.php?tid=80247&highlight=24fps)

audio sync at 24fps (https://emby.media/community/index.php?/topic/48226-audio-sync-at-24fps/)

I'm not sure if this is relevant to anyone else, but thought I'd ask.

[iSeries]

^^^ Great idea, I too have the same issue at 24p.

I have a "display manager" planned. But this is a big and difficult job that I do not know when we start doing.

[Schrade]

I am using MPC-BE as my video player for Twitch Streams via Streamlink-Twitch-GUI (https://streamlink.github.io/streamlink-twitch-gui/)

When I try to take a screenshot using F5, it says a screenshot has been saved but it doesn't get saved. I think it might have something to do with the .m3u8 filename in the URL being 770 characters long.

Any chance we could have a setting to configure the screenshot filenames? Or perhaps there's another way around this?
